Amongst my collection I have most of the penguin/polarware games, and was looking on ebay recently to fill some gaps. I found a copy of Pie Man with the penguin branding, which I knew was different to the one I had. I checked and mine is branded bearware. I know that penguin changed to polarware given a ruckus with the book publishing company, but could find almost nothing on bearware. The polarware
website doesn't mention it, and while it shows up here
it doesn't say anything about why or what it was.
The penguin branded version was released in 1982, and according to that latter site, the bearware version was published in 1987, which was around the time Merit bought polarware (1987). I wandered whether perhaps it was a re-release after the company purchase, but really have no idea.
I also note that my bearware copy has no publishing date, but says "copyright 1982 penguin software". Its sealed so I can't look inside for further info.
Can anyone shed any light?
